Testing the SDK During the Integration

You can test the SDK throughout your integration process and even before the integration. To test the SDK before the integration, we encourage you to use Passio's Reference App bundled with the SDK.

After you build the reference app or get the recognition to work inside of your app, you can test that the technology is working properly by pointing the phone at at parts of the image below to test recognition. You can test the following elements:

  • Food (non packaged)

  • Barcode

  • Packaged food

  • Nutrition facts

You can find a more extensive test of packaged and unpackaged foods below.

When testing the reference App, don't forget to add your key to the PassioExternalConnector class

class PassioExternalConnector 

var passioKeyForSDK: String {
